Abstract: A method for a wireless UE device to utilize tokens and cloud service technology to facilitate the provision of location data to an emergency call center. The UE may provide cellular signaling to initiate an outgoing telephone call to an emergency call center. A token may be provided during the signaling, wherein the token is associated with location information of the UE device stored on a server computer (referred to as a cloud server or location server). The token may uniquely identify the UE device and/or a user cloud service account of the UE device. The call center may use the token to retrieve location information of the UE from the cloud server. The use of the token may also provide for enhanced security, e.g., to prevent spoofing of the UE phone number.

Abstract: A communications network may be used to convey Short Message Service (SMS) messages using the Internet Protocol (IP). User equipment may transmit an SMS-over-IP Session Initiation Protocol (SIP) message to wireless equipment over a high-bandwidth communications link. The wireless equipment may route the SMS-over-IP SIP message to the ePDG. When the high-bandwidth link is unavailable, the user equipment may transmit a compressed message to the proxy server over a low-bandwidth communications link. The proxy server may convert the compressed message into an SMS-over-IP SIP message that is transmitted to the ePDG. The proxy server may serve as a proxy for the first user equipment from the perspective of the ePDG. This may allow SMS message data to continue to be conveyed through the communications network even when the high-bandwidth communications link becomes unavailable.
